Serial Communication Appliance for Scada Systems

IPC hardware manufacturer Lanner Electronics has released the LEC-3010, a small form factor serial communication appliance built for Scada systems. It features six serial ports, four GbE LAN ports and utilises Intel Atom N450 CPU. The LEC-3010 was designed for easy installation and minimal upkeep, according to Lanner. It was also designed to meet the need for cost-effective, highly adaptive small form factor IPCs in Scada communications applications.

The LEC-3010 is DIN rail-mountable and can rotate along its DIN-rail attachment. Ease of access was a key consideration in the design of the LEC-3010 and other features that highlights this are the Compactflash socket and easily readable LED lights. The Compactflash card can be removed from the system without opening the chassis and the LED lights clearly display information about the COM and LAN ports. There are a total of six serial (COM) ports and four GbE LAN ports along the front face.

The serial ports are connected via phoenix contacts that screw down to ensure a steady connection. The COM ports can send and receive signals using RS-232/422/485 protocols. Switching between these signals can be achieved onboard through the hardware autoflow control. The RJ-45 LAN ports all use Realtek network controllers. The rugged LEC-3010 can withstand high-temperature variation, features a cable-less interior and wide power-input range. When utilised with industrial components (Compactflash and memory), the LEC-3010 can run in conditions ranging from -20C~55C.

The cable-less and fan-less design ensure product longevity by eliminating the two main reasons for IPC malfunction. The appliance can support direct current of +12~36V inputs. The product is built around the ultra-low-power-consuming Intel Atom N450 CPU and can hold up to 2GB of memory through a single Sodimm slot. Other communication features include: two USB 2.0 ports; Dido port and VGA display port. There is also an onboard watchdog timer. This platform is compatible with both Windows and Linux operating systems.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
